Asarabacca and Triamterene

Here is the interaction we found between these two, with the evidence behind it.

Major

Nephrotoxic Drugs

Why this applies to Triamterene

Triamterene falls under Nephrotoxic Drugs — the group Asarabacca interacts with.

Asarabacca, a herbaceous plant, is often contaminated with aristolochic acid, a compound known for its nephrotoxic effects. Aristolochic acid can damage the kidneys and is deemed unsafe by the FDA, leading to the classification of products containing it as adulterated. When considering medications that may also pose a risk of kidney damage, caution is advised when combining them with asarabacca due to potential additive nephrotoxicity. It is advisable to consult healthcare professionals before using asarabacca alongside nephrotoxic drugs to minimize the risk of adverse effects on kidney function.
Severity Major Likelihood Possible Evidence C

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing asarabacca and triamterene. Asarabacca often contains aristolochic acid, a compound the FDA flags as unsafe because it can seriously harm your kidneys. Triamterene is a water pill that works through your kidneys and can already stress them, so stacking these two together may add up to more kidney trouble than either alone.

This isn't about asarabacca changing how triamterene is broken down. It's the combined burden on your kidneys. Watch for warning signs like swelling that gets worse, less urine, or feeling unusually tired. Triamterene can also push potassium up, and struggling kidneys make that risk higher. Honestly, I'd steer clear of asarabacca entirely, but please talk with your doctor or pharmacist before combining them.

From our pharmacist’s overview on the Triamterene page

“Because triamterene (Dyrenium) both lowers blood pressure and hangs onto potassium, its supplement list calls for real vigilance. Six of the 165 ingredients on file carry a major rating, and those six deserve your attention before any others.”

About Asarabacca

What is Asarabacca?

Asarabacca
  • Sinus and nasal congestion
  • Coughs and bronchial complaints
  • Inducing sweating
  • Inducing vomiting (emetic)
  • Digestive upset

Asarabacca is a European woodland plant traditionally used to clear the nose, cause sweating, or trigger vomiting, but it is rarely used today. It belongs to a plant family that often contains aristolochic acid, a substance the FDA considers unsafe because it can cause serious kidney damage and cancer, so we do not recommend using it.

About Triamterene

What Is Triamterene Used For?

Brand name: Dyrenium

Triamterene capsules are used to treat edema — excess fluid buildup in the body — linked to several conditions, including congestive heart failure, cirrhosis of the liver, and nephrotic syndrome (a kidney disorder causing protein loss and swelling). It is also used for steroid-induced edema, idiopathic edema (fluid retention with no clear cause), and edema due to secondary hyperaldosteronism (overproduction of a hormone that causes the body to hold onto sodium and water).

It can be used on its own or alongside other diuretics, either to boost fluid removal or to help preserve potassium levels. Both Dyrenium and Triamterene capsules share the same approved uses as described above.
